WebAn AC adjustable sped drive changes the frequency of the voltage applied to a motor by taking the incoming D.C. VOLTAGES converting it to an Ac voltage and inverting it back to a variable frequency D.C. True or false. False. The simplest way to adjust the drive output is to set an internal reference voltage.
WebA linear rheostat is a two-terminal variable resistor in which the sliding contact, or wiper, is attached to a wire coil running in a straight line along an insulating cylinder. The mechanical operation of a linear rheostat thus takes the form of a two-way slider. They are often called slide rheostats (or sliding rheostats) for this reason.
